NewsBlur is mentioned in the article, but I cannot overstate how positive my experience with DigitalOcean has been. I'm stressing their biggest machines and spinning up dozens of differently configured boxes and they've handled it swimmingly well. Between the price and the performance differences, I'm glad I switched.
I also have a shadow site running in parallel on EC2, so I get to compare dollar for dollar. EC2 is strictly an apocalypse host at this point.
